John Macnab: Author Thirty Nine Steps

John Buchan published his second most famous novel, John MacNab. 

Three high-flying men—a barrister, a cabinet minister, and a banker—are suffering from boredom. They concoct a plan to cure it. They inform three Scottish estates that they will poach from each two stags and a salmon in a given time. They sign collectively as "John McNab" and await the responses. 

This novel is a light interlude within the Leithen Stories series—an evocative look at the hunting, shooting and fishing lifestyle in Highland Scotland.
